The Information Telecommunication System "Solaris" was created to solve the actual problems of navigation. The system allows analyzing an operational local and synoptic hydrometeorological situation on a vessel route to issue recommendations to navigators about the optimization of the movement from the point of view for the safety of navigation and economic efficiency. ITS "Solaris" represents a combination of two hardware-software complexes one of which is fitted on the vessel, and the other one ashore. The ship complex is based on the use of regular ship radar station to which AD converter and the computer with the software is connected. The coastal complex is a server that collects, processes, analyzes stores and transmits satellite and ship information. To operate the system on a particular ship the proposed model calculates the speed of the vessel, depending on the direction and speed of meteorological parameters such as wind, waves and currents, of ice conditions. The system can be used in the initial planning of the route on the basis of operational and climatic data according to the seasonal variability of the weather conditions. The created system improves the safety of navigation and increase economic efficiency.
